Circumcision question

M
Not looking for an advice or feedback on the decision of doing it..just wondering if any moms on here have had experience with it before. I'm curious as to how we go about letting them know we want it done? Do we just tell them once we get there on the day of delivery or is it something I notify my doctor of now before my due date gets here? I have already checked with my insurance and they cover it, I just don't know what steps to take from here
